Teledyne AVCR1360 Variable compression engine

[slabbowl]

Ive been looking for information regarding the AVCR1360-2 Variable Compression Engine, I know its a diesel inline 6 but thats about it, ive also had a brief memory of it being used in the General Motors XM1 Tank prototype, although this could be a Mandela effect
any more information would help. (if it even exists or is a figment of my rotting minds imagination)

Hi,

I do have more information, but takes sone time... The engine had special pistons which adepted to the combustion pressure (basically a highly damped spring under the piston crown). With this indirect control, the system works slow and with big deviations among the cylinders. There are better systems available. One of the better ones(not really the best) even made it into production by Nissan.
